Parasites and biological organisms have had a role to play in human medicine for thousands of years:

  • Leeches were used as a vital tool in clinical bloodletting by ancient Indian and Greek physicians as far back as 500BC – in the 1980s, this type of treatment resurfaced, with current applications including use in reconstructive surgery and microsurgery, both of which can benefit from wounds which allow blood to continuously flow, instead of pooling.
  • Maggots seen use by the Maya civilisation and Aboriginal peoples of Australasia as a treatment for open wounds: this technique was lost for many years, but resurfaced centuries later as a useful treatment on the battlefields of the Napoleonic Wars, the US civil war and in the trenches during WWI.
  • The Garra rufa fish, (also known as the Kangal Fish) has been used to treat dermatological conditions such as dermatitis and psoriasis – the effects of lying in a pool with these fish were first observed in Turkey, with the treatment, known as ‘Ichthyotherapy’ becoming a popular addition to health spas (and even shopping centres) around the world.

Hookworms, then, are not the first organisms which the medical community have used for the good of mankind: however, this humble parasite has a very important role to play in our understanding of what can be done to treat autoimmune diseases and immune disorders – but what exactly are hookworms and how can they help?

What are hookworms?
Hookworms are a type of helminth (parasitic worm) which measure anywhere between 5mm and 10mm in length – the creatures normally enter their host by using their well-developed jaws to burrow through the skin, commonly through the sole of the foot – from their entry point, the worms work their way up into the lungs, onwards to the trachea, where they are then swallowed: at this point, they make their way into the digestive system of their host, where they set root in the intestines – from this base of operations, they can comfortably mate and dwell unharmed, laying tens of thousands of eggs per day with impunity, with a potential to lay up to 60 million in their lifetime.

How can hookworms be used in modern medicine?
Studies have shown that sufferers of Multiple Sclerosis, Crohn’s disease and Coeliac disease could benefit from a mild hookworm infestation: this ties in to the hygiene hypothesis, where a lack of childhood exposure to parasites and microorganisms is commonly linked to a less developed immune system: essentially, by introducing hookworms, the hope is that an individual will start to develop an improved immune response.

The worms are commonly administered via skin patches, where they will enter the body as they would in nature – once a patient has lived with the worms present in their gut for the best part of a year, the parasites are disposed of by administering a worming medicine;

Studies are still being carried out in this hot area of research – however, a number of findings will start to be published in coming years: by then, we may see more and more natural parasites being used in medicine, along with improved drugs and herbal treatments.
